[0016] In the above technical solution, the air-pressure shock absorber is matched with the lightweight characteristics of the aluminum alloy frame, which improves the overall ease of riding, and the air pressure adjustment function provides flexible shock absorption effect to adapt to different road conditions and riding styles.

[0017] Preferably, the riser has a through hole for the limiting block to pass through.

[0018] In the above technical solution, the through holes facilitate disassembly and adjustment, making it convenient to maintain or replace the rear fork or shock absorber.

[0019] Preferably, the fixing block is welded to the outer periphery of the riser.

[0020] In the above technical solution, by welding a fixing block, the shock absorber can be tightly connected to the riser, so that the shock absorber can more directly absorb and disperse the vibration during riding.

[0022] 1. This lightweight, high-strength aluminum alloy bicycle frame features a triangularly designed rear fork that effectively disperses various forces generated during riding, allowing the rear fork to maintain a stable structure even on complex road conditions. At the same time, the rear fork transmits vibrations to the shock absorber through a movable support block.

[0034] In the above technical solution, the rear fork 7 with its triangular design can effectively disperse various forces generated during riding, so that the rear fork 7 can still maintain a stable structure under complex road conditions. At the same time, the rear fork 7 transmits vibration to the shock absorber 10 through the movable support block 8. The shock absorber 10 achieves shock absorption through the pressure of sealed gas, which can effectively reduce the transmission of vibration to the rider's body and improve riding comfort.

[0035] Preferably, the head tube 1, front fork 2, frame 3, seat tube 4, down tube 6, and rear fork 7 are made of aluminum alloy materials in a specific proportion, which contain aluminum, magnesium, silicon, and other trace elements. In the above technical solution, aluminum alloy composed of aluminum (Al), magnesium (Mg), and silicon (Si) as the main elements is selected as the raw material, wherein the proportion of Mg and Si is precisely controlled to obtain the best strength and lightweight effect.

[0036] Preferably, the aluminum alloy material undergoes a T6 heat treatment process. In the above technical solution, the T6 heat treatment process strengthens the internal structure of the aluminum alloy material, giving it better tensile strength and fatigue resistance.

[0042] Working principle: The triangular design of the rear fork 7 effectively disperses various forces generated during riding, allowing it to maintain structural stability even on complex road conditions. Simultaneously, the rear fork 7 transmits vibrations to the shock absorber 10 via the movable support block 8. The shock absorber 10 uses the pressure of sealed gas to dampen shocks, effectively reducing vibration transmission to the rider's body and improving riding comfort. It uses an aluminum alloy composed primarily of aluminum (Al), magnesium (Mg), and silicon (Si) as raw material, with the Mg and Si ratio precisely controlled to achieve optimal strength and lightweight properties.
